my mother is 81 years old, she has recently started getting confused with things like not remembering if she has taken her med. she was very weak and blood pressure very low and heart rate very low, doctor put her in the hospital for 4 nights to build up her fluids which helped and they changed her med. took her off two blood pressure med. now only on one. my concern is she takes thyroid med. I am afraid with her age and her weight 121. she no longer needs this med.
